BACKGROUND

Communication systems can be grouped into wireline communication systems, wireless communication systems, and hybrid communication systems. Wireline communication systems rely on a tangible communication medium, such as an optical cable, a coaxial electrical cable, and/or a twisted-pair electrical cable, to transmit data. Wireless communication systems do not require a tangible communication medium, and wireless communication systems transmit data using techniques such as optical and radio frequency data transmission. Hybrid wireline-wireless communication systems include at least one wireline communication system and at least one wireless communication system.

Both wireline and wireless communication systems often include two or more communication channels. For example, a base station in a wireless communication system may transmit data via a plurality of communication channels in the form of wireless subcarriers. As another example, each wireless base station of an array of wireless base stations may transmit data via a respective communication channel. As yet another example, a digital subscriber line access multiplexer (DSLAM) may communicate with multiple clients via respective communication channels in the form of twisted-pair cables.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Operation of one communication channel or path in a communication system will often affect operation of other communication channels or paths in the communication system. For example, a wireless base station configured to transmit data via a plurality wireless subcarriers typically has a total transmission power that must be allocated among the wireless subcarriers. Allocation of transmission power to one subcarrier necessarily affects the other subcarriers by limiting available transmission power to the other subcarriers. As another example, there may be interference between wireless base stations in an array of wireless base stations, such that operation of one wireless base station may affect operation of other wireless base stations in the array. As yet another example, there may be cross-talk between, for example, twisted-pair electrical cables in a common cable bundle, such that transmission of data through one twisted-pair electrical cable in the bundle may affect operation of another twisted-pair electrical cables in the bundle.

Disclosed herein are methods, devices, and systems for dynamic allocation of communication resources. The disclosed methods, devices, and systems, for example, automatically allocate communication resources among communication channels in a manner that helps maximize return (e.g., data throughput) and/or minimize risk (e.g., variation in data throughput). Certain embodiments consider stochastic properties of the communication channels to help optimize communication resource allocation in a dynamic operating environment.

FIG. 1 is a block diagram of a communication system 100 configured to perform dynamic allocation of communication resources. Communication system 100 includes a first communication device 102 and a second communication device 104 communicatively coupled via N communication channels 106. Although FIG. 1 shows N being greater than two, N can be any integer greater than one. In this document, specific instances of an item may be referred to by use of a numeral in parentheses (e.g., communication channel 106(1)) while numerals without parentheses refer to any such item (e.g., communication channels 106). Communication channels 106 are, for example, wireline communication channels, wireless communication channels, or hybrid wireline-wireless communication channels. In some embodiments, each communication channel 106 includes a respective physical communication medium, such as a respective optical cable or a respective electrical cable. In some other embodiments, at least two communication channels 106 share a common communication medium. For example, in certain embodiments, each communication channel 106 represents a respective communication signal transmitted through a common communication medium, such as air, an electrical cable, or an optical cable. As another example, in some embodiments, each communication channel 106 represents a respective subcarrier of a communication signal transmitted through a common communication medium, such as air, an electrical cable, or an optical cable.

Each communication channel 106 need not necessarily have the same configuration. For example, in one configuration, communication channel 106(1) is a wireless communication channel, and communication channel 106(2) is a wireline communication channel. Although FIG. 1 depicts communication channels 106 are being one-way communication channels, i.e. transferring data from first communication device 102 to second communication device 104, communication channels 106 could be two-way communication channels without departing from the scope hereof.

First communication device 102 includes a transmitting subsystem 108, a processing subsystem 110, and a memory subsystem 112. Transmitting subsystem 108 is configured to generate a plurality of signals, e.g. radio-frequency signals for wireless transmission, electrical signals for transmission via one or more electrical cables, and/or optical signals for transmission via one or more optical cables, for transmission to second communication device 104 via respective communication channels 106. Processing subsystem 110 is configured to execute instructions 114 stored in memory subsystem 112 to control at least some aspects of first communication device 102. For example, in some embodiments, processing subsystem 110 is configured to execute instructions 114 to execute a method 200 for dynamic allocation of communication resources, which is discussed below with respect to FIG. 2. Instructions 114 include, for example, software and/or firmware.

Although each of transmitting subsystem 108, processing subsystem 110, and memory subsystem 112 is symbolically shown as a single element, one or more of these elements may include a plurality of constituent sub-elements. For example, transmitting subsystem 108 could include a plurality of transmitters, processing subsystem 110 could include a plurality of processors, and memory subsystem 112 could include a plurality of memory modules. Additionally, the elements and sub-elements of first communication device 102 could be distributed in multiple locations. For example, processing subsystem 110 could include multiple processors distributed among two or more data centers, and memory subsystem 112 could include multiple memory devices distributed among a plurality of data centers. Furthermore, transmitting subsystem 108 could be capable of receiving signals, as well as generating signals, without departing from the scope hereof.

First communication device 102 may include additional elements without departing from the scope hereof. In some embodiments, first communication device 102 is one of (a) a wireless base station, e.g. a long-term evolution (LTE) wireless base station (e.g., an eNB device), a fifth-generation (5G) new radio (NR) wireless base station (e.g., a gNB device), an Integrated Access Backhaul (IAB) base station, a sixth-generation (6G) wireless base station, a Wi-Fi wireless base station (e.g., including unscheduled, partially scheduled, and scheduled systems), a satellite wireless base station, or variations and/or extensions thereof, (b) a modem termination system, e.g. a cable modem termination system (CMTS), a wireless core (such as a mobile core, a Wi-Fi core, a converged core, etc.), a DSLAM, etc., (c) an optical line terminal (OLT), e.g. operating according to a ethernet passive optical network (EPON) protocol, a radio frequency over glass (RFOG) protocol, or a gigabit passive optical network (GPON) protocol, (d) an access device, e.g. a cable modem, such as operating according to a data over cable service interface specification (DOCSIS) protocol, a DSL modem, or an optical network unit (ONU) or an optical network terminal (ONT), such as operating according to an EPON protocol, a RFOG protocol, or a GPON protocol, a wireless access device (including, for example, eNBs, gNBs, and IAB access point, microcell, picocell, femtocell, macrocell, Wi-Fi Aps, etc), or (e) a UE device, e.g. a computer, a set-top device, a data storage device, an Internet of Things (IoT) device, an entertainment device, a computer networking device, a mobile telephone, a smartwatch, a wearable device with wireless capability, a medical device, etc. In some embodiments, first communication device 102 is part of another device, and first communication device 102 may share one or more components, e.g. processing subsystem 110 and/or memory subsystem 112, with such other device.

Second communication device 104 includes a receiving subsystem 116, a processing subsystem 118, and a memory subsystem 120. Receiving subsystem 116 is configured to receive signals from transmitting subsystem 108 via communication channels 106. In some embodiments, receiving subsystem 116 is also configured to generate signals, called, for example, a transceiving subsystem. Processing subsystem 118 is configured to execute instructions 122 stored in memory subsystem 120 to control at least some aspects of second communication device 104. Instructions 122 include, for example, software and/or firmware.

Although each of receiving subsystem 116, processing subsystem 118, and memory subsystem 120 is symbolically shown as a single element, one or more of these elements may include a plurality of constituent sub-elements. For example, receiving subsystem 116 could include a plurality of receivers, processing subsystem 118 could include a plurality of processors, and memory subsystem 120 could include a plurality of memory modules. Additionally, the elements and sub-elements of second communication device 104 could be distributed in multiple locations. For example, processing subsystem 118 could include multiple processors, either co-located or distributed, and memory subsystem 120 could include multiple memory devices, either co-located or distributed.

Second communication device 104 may include additional elements without departing from the scope hereof. In some embodiments, second communication device 104 is part of one of (a) a modem termination system, e.g. a CMTS or a DSLAM, (b) an OLT, e.g. operating according to a EPON protocol, a RFOG protocol, or a GPON protocol, (c) an access device, e.g. a modem, such as operating according to a DOCSIS protocol, a DSL modem, or an ONU or ONT, such as operating according to an EPON protocol, a RFOG protocol, or a GPON protocol, (d) a UE device, e.g. a computer, a set-top device, a data storage device, an IoT device, an entertainment device, a wireless access point (including, for example, eNBs, gNBs, and Wi-Fi APS acting as UEs), a computer networking device, a mobile telephone, a smartwatch, a wearable device with wireless capability, and a medical device, (e) a wireless base station, e.g. a LTE wireless base station (e.g., an eNB device), a 5G NR wireless base station (e.g., a gNB device), a 6G wireless base station, a Wi-Fi base station (e.g., including unscheduled, partially scheduled, and unscheduled systems), a satellite wireless base station, or variations and/or extensions thereof, or (f) an array of wireless base stations. In some embodiments, second communication device 104 is part of another device, and second communication device 104 may share one or more components, e.g. processing subsystem 118 and/or memory subsystem 120, with such other device.

Referring again to first communication device 102, in some embodiments, processing subsystem 110 is configured to execute instructions 114 to control transmitting subsystem 108 to automatically allocate communication resources (e.g., transmission power and/or communication capacity) among communication channels 106 in a manner that helps maximize return (e.g., data throughput) and/or minimize risk (e.g., variation in data throughput). For example, in some embodiments, processing subsystem 110 is configured to execute instructions 114 to perform method 200 of FIG. 2 for dynamic allocation of communication resources. In a block 202 of method 200, processing subsystem 110 executes instructions 114 to determine a risk-return characterization of a plurality of communication resource allocations. In some embodiments, the risk-return characterization includes a respective risk and a respective return for each communication resource allocation. Each return is, for example, total data throughput of all communication channels 106, and each risk is, for example, a variation in total data throughput of all communication channels 106. Each communication resource allocation specifies how one or more communication resources are allocated among communication channels 106. For example, in some embodiments, each communication resource allocation specifies how a total transmission power is allocated among communication channels 106, and in some other embodiments, each communication resource allocation specifies how total communication capacity is allocated among communication channels 106. In some embodiments, processing subsystem 110 executes instructions 114 to randomly generate the plurality of communication resource allocations.

The number of communication resource allocations considered in block 202 is chosen, for example, to achieve a desired trade-off between optimization of communication resource allocation and minimization of processing time. Determining a risk-return characterization of many communication resource allocations in block 202 promotes optimization of communication resource allocation, while determining a risk-return characterization of few communication resource allocations in block 202 helps minimize load on processing subsystem 110.

Table 1 below illustrates one example of a risk-return characterization determined in block 202, in an embodiment where there are three communication channels 106 (N=3) and a risk-return characterization is determined for fourteen communication resource allocations A₁, A₂, A₃, . . . . A₁₄. Each communication resource allocation A₁ corresponds to a particular set of weights, i.e. A_(i)={W_(i1), W_(i2), W_(i3)}, where the letter “i” is an index which ranges from 1 to 14 and corresponds to a particular communication resource allocation. W_(i1), W_(i2), and W_(i3) represent a portion of total communication resources allocated to communication channels 106(1), 106(2), and 106(3), respectively. For example, communication resource allocation A₁ corresponds to 10%, 10%, and 80% of total communication resources being allocated to communication channels 106(1), 106(2), and 106(3), respectively. Accordingly, if the communication resource being allocated is 1.0 watts of total transmission power, 0.1 watt, 0.1 watt, and 0.8 watt of transmission power would be allocated to communication channels 106(1), 106(2), and 106(3), respectively, under communication resource allocation A₁. As another example, communication resource allocation A₂ corresponds to 10%, 40%, and 50% of total communication resources being allocated to communication channels 106(1), 106(2), and 106(3), respectively. Accordingly, if the communication resource being allocated is 1.0 watts of total transmission power, 0.1 watt, 0.4 watt, and 0.5 watt of transmission power would be allocated to communication channels 106(1), 106(2), and 106(3), respectively, under communication resource allocation A₂. It should be appreciated, however, that communication resources other than transmission power may be considered in block 202. For example, in another embodiment, the plurality of communication resource allocations specify how total communication system capacity is allocated among communication channels 106.

Processing subsystem 110 executes instructions 114 to determine a respective return (R_(i)) and a respective risk (V_(i)) for each communication resource allocation A_(i) in the example of Table 1. For example, processing subsystem 110 determines that return R₁ and risk V₁ for communication resource allocation A₁ are 0.650 and 0.600, respectively, and processing subsystem 110 determines that the return R₂ and risk V₂ for communication resource allocation A₁ are 0.600 and 0.500, respectively. R_(i) represents total data throughput of all communication channels 106 using communication resource allocation A_(i), and V_(i) represents variation in total data throughput of all communication channels 106 using communication resource allocation A_(i). In some embodiments, processing subsystem 110 executes instructions 114 to determine return R_(i) and risk V_(i) from EQNS. 1 and 2, below respectively.

R _(i)=Σ_(a=1) ^(N) W _(ia) E _(ia)  (EQN. 1)

V _(i)=Σ_(a=1) ^(N) W _(ia) ²σ_(ia) ²+Σ_(a=1) ^(N)Σ_(b=1≠a) ^(N) W _(ia) W _(ib)σ_(ia)σ_(ib)ρ_(iab)  (EQN. 2)

In EQN. 1, E_(ia) is an expected return, e.g. data throughput, for communication channel 106(a) with communication resource allocation A_(i), where ‘a’ ranges from 1 to N. N is the number of communication channels 106 in communication system 100, as stated above. In some embodiments, processing subsystem 110 executes instructions 114 to determine E_(ia) from historical performance data of communication system 100, e.g. at least partially based on performance data determined by second communication device 104 and transmitted to first communication device 102. In EQN. 2, σ_(ia) is variation in return for communication channel 106(a) with communication resource allocation A_(i), and σ_(ib) is variation in return for communication channel 106(b) with communication resource allocation A_(i). Each of a and b ranges from 1 to N in EQN. 2. ρ_(iab) is the correlation coefficient between communication channels 106(a) and 106(b) with communication resource allocation A_(i). In some embodiments, processing subsystem 110 executes instructions 114 to determine σ_(ia), σ_(ib), and ρ_(iab) from historical performance data of communication system 100, e.g. at least partially based on performance data determined by second communication device 104 and transmitted to first communication device 102.

TABLE 1 Allocation W_(i1) W_(i2) W_(i3) R_(i) V_(i) A₁ 10% 10% 80% 0.650 0.600 A₂ 10% 40% 50% 0.600 0.500 A₃ 20% 10% 70% 0.600 0.675 A₄ 20% 30% 50% 0.450 0.650 A₅ 40% 30% 30% 0.525 0.400 A₆ 50% 30% 20% 0.500 0.425 A₇ 40% 10% 50% 0.500 0.600 A₈ 40% 50% 10% 0.400 0.400 A₉ 70% 10% 20% 0.350 0.500 A₁₀ 70% 20% 10% 0.425 0.300 A₁₁ 80% 10% 10% 0.250 0.300 A₁₂ 100%  0 0 0.300 0.250 A₁₃ 0 100%  0 0.525 0.475 A₁₄ 0 0 100%  0.675 0.700

FIG. 3 is a graph 300 of return as a function of risk from the data of Table 1. Each point on graph 300 corresponds to a respective value of R_(i) and V_(i) for a particular communication resource allocation A_(i) of Table 1. For example, point 302 corresponds to a return of 0.250 and a risk of 0.300 for communication resource allocation A₁. The remaining points are not labeled in FIG. 3 to promote illustrative clarity.

It can be observed from FIG. 3 that more than one possible return R₁ may be realized at a given risk V_(i). Similarly, there may be more than one possible risk V_(i) at a given return R_(i). Curve 304 represents a maximum return R_(i) that may be achieved for a given risk V_(i) among communication resource allocations A₁, A₂, A₃, . . . . A₁₄. Curve 304 also represents a minimum risk V_(i) that be realized at a given return R_(i) among communication resource allocations A₁, A₂, A₃, . . . . A₁₄. Curve 304 may be referred to as an efficiency frontier.

Referring again to FIG. 2, in block 204, processing subsystem 110 executes instructions 114 to select a first allocation of the plurality of communication resource allocations from the risk-return characterization, according to at least one predetermined criterium. In some embodiments, the predetermined criterium is either a maximum return that can be achieved at a given risk or a minimum risk that can be realized at a given return. For example, assume that the predetermined criterium is to achieve maximum return at a risk of 0.500, given the scenario discussed above with respect to Table 1. The first allocation would be communication resource allocation A₂ because this communication resource allocation is on the efficiency frontier and achieves a maxim return (0.600) at a risk of 0.500, as can be seen in FIG. 3. As another example, assume that the predetermined criterium is to realize a minimum risk at a return of 0.525, assuming the scenario discussed above with respect to FIG. 1. The first allocation would be communication resource allocation A₅ because this communication resource allocation is on the efficiency frontier and achieves a minimum risk (0.400) at a return of 0.525, as can be seen in FIG. 3. Such selection of a communication resource allocation from a risk-return characterization advantageously accounts for stochastic properties of communication channels 106 when determining a communication resource allocation.

In block 206, processing subsystem 110 executes instructions 114 to automatically allocate communication resources among the plurality of communication channels according to the first allocation. For example, assume that communication resource allocation A₂ of Table 1 is selected as the first allocation in block 204. In this example, processing subsystem 110 executes instructions 114 to automatically allocate communication resources among communication channels 106(1), 106(2), 106(3) according to set of weights {10%, 40%, 50%} of communication resource allocation A₂. For example, if the communication resource to be allocated is a of 0.5 watt of total transmission power, processing subsystem 110 executes instructions 114 to control transmitting subsystem 108 such that 0.05 watt, 0.20 watt, and 0.25 watt are allocated to communication channels 106(1), 106(2), 106(3), respectively. As another example, if the communication resource to be allocated is a total communication capacity of 10 Gigabits (Gb) per second (s) for communication system 100, processing subsystem 110 executes instructions 114 to control transmitting subsystem such that 1.0 Gb/s, 4.0 Gb/s, and 5.0 Gb/s are allocated to communication channels 106(1), 106(2), 106(3), respectively. Accordingly, execution of method 200 may result in allocation of communication resources among communication channels in a manner which corresponds to an efficiency frontier, thereby helping optimize allocation of the communication resources.

Table 2 below illustrates another example of a risk-return characterization determined in block 202 by processing subsystem 110 executing instructions 114, in an embodiment where there are four communication channels 106 (N=4) and a risk-return characterization is determined for fifteen communication resource allocations A₁, A₂, A₃, . . . . A₁₅. Analogous to Table 1, each communication resource allocation A₁ in Table 2 corresponds to a particular set of weights, i.e. A_(i)={W_(i1), W_(i2), W_(i3), W_(i4)}, where the letter “i” is an index which ranges from 1 to 15 and corresponds to a particular communication resource allocation. W_(i1), W_(i2), W_(i3), W_(i4) represent a portion of total communication resources allocated to communication channels 106(1), 106(2), 106(3), and 106(4), respectively. Additionally, R_(i) corresponds to respective return, and V_(i) corresponds to respective risk, for communication resource allocation A_(i) in a manner like that discussed above with respect to Table 1.

TABLE 2 Allocation W_(i1) W_(i2) W_(i3) W_(i4) R_(i) V_(i) A₁ 10% 30% 20% 40% 0.100 0.325 A₂ 15% 25% 40% 20% 0.225 0.175 A₃ 20% 40% 10% 30% 0.525 0.400 A₄ 15% 25% 30% 30% 0.125 0.250 A₅ 17% 23% 25% 35% 0.600 0.500 A₆ 30% 30% 15% 25% 0.300 0.300 A₇ 30% 30% 20% 20% 0.300 0.200 A₈ 25% 35% 20% 20% 0.425 0.300 A₉ 35% 40% 20%  5% 0.375 0.475 A₁₀ 40% 20% 10% 30% 0.225 0.400 A₁₁ 40% 25% 15% 20% 0.425 0.400 A₁₂ 25% 10% 30% 35% 0.675 0.700 A₁₃ 38% 25% 17% 20% 0.525 0.500 A₁₄ 30% 50%  5% 15% 0.650 0.600 A₁₅ 25% 25% 25% 25% 0.575 0.600

FIG. 4 is a graph 400 of return as a function of risk from the data of Table 2, and curve 404 represents an efficiency frontier of the risk-return characterization of Table 2. Processing subsystem 110 executes instructions 114 to (a) select a first allocation of the plurality of communication resource allocations from the risk-return characterization of Table 2 and (b) automatically allocate communication resources among the plurality of communication channels 106 according to the determined first allocation, in a manner similar to that discussed above with respect to Table 1. For example, if the predetermined criterium is to achieve minimum risk at a return of 0.250, processing subsystem 110 executes instructions 114 to (a) to select resource allocation A₂ as the first allocation, because this resource allocation is on the efficiency frontier 404 and achieves a minimum risk (0.175) at a return of 0.250, and (b) automatically allocate communication resources among communication channels 106 according to resource allocation A₂.

In some embodiments, first communication device 102 is configured to execute instructions 114 to perform method 200 periodically and/or in response to a change in operating conditions of communication system 100. Such repeated performance of method 200 advantageously helps communication system 100 adapt to changes in its operating environment, thereby promoting high-performance of communication system 100 under dynamic conditions.

In some embodiments, processing subsystem 118 is further configured to execute instructions 122 to automatically allocate communication resources (e.g., transmission power and/or communication capacity) among communication channels which transfer data from second communication device 104 to first communication device 102, in a manner which helps maximize return (e.g., data throughput) and/or minimize risk (e.g., variation in data throughput). In some of these embodiments, communication channels 106 are bidirectional such that both downlink and uplink data may be transmitted between first communication device 102 and second communication device 104. In some other embodiments, communication channels (not shown) in addition to communication channels 106 are used to transfer uplink data. Downlink data is data transferred from first communication device 102 to second communication device 104, and uplink data is data transferred from second communication device 104 to first communication device 102. In some embodiments, processing subsystem 118 is configured to execute instructions 122 to perform a method similar to method 200 of FIG. 2, to automatically allocate communication resources (e.g., transmission power and/or communication capacity) among uplink communication channels.

FIG. 5 is a block diagram of a communication system 500, which is one embodiment of communication system 100 (FIG. 1) where (a) first communication device 102 is embodied as a wireless base station 502 and (b) second communication device 104 is embodied as a UE device 504. Wireless base station 502 is, for example, a LTE wireless base station (e.g., an eNB device), a 5G NR wireless base station (e.g., a gNB device), a 6G wireless base station, a Wi-Fi wireless base station (e.g., including unscheduled, partially scheduled, and unscheduled systems), a satellite wireless base station, or variations and/or extensions thereof. Although UE device 504 is depicted as a mobile phone, UE device 504 can take a different form, such as a computer, a set-top device, a data storage device, an IoT device, an entertainment device, a wireless access point (including, for example, eNBs, gNBs, and Wi-Fi APS acting as UEs), a computer networking device, a smartwatch, a wearable device with wireless capability, or a medical device.

Wireless base station 502 includes a transmitting subsystem 508, a processing subsystem 510, and a memory subsystem 512, which are embodiments of transmitting subsystem 108, processing subsystem 110, and memory subsystem 112, respectively. Transmitting subsystem 508 includes a transceiver 524 electrically connected to an antenna assembly 526. Transceiver 524 and antenna assembly 526 are collectively configured to generate a plurality (N) of radio frequency (RF) wireless subcarriers 506 of a multi-carrier modulation (MCM) signal in response to electrical or optical signals from processing subsystem 510. Wireless subcarriers 506 are embodiments of communication channels 106 of FIG. 1, and wireless subcarriers 506 wirelessly transmits information from wireless base station 502 to UE device 504. In some embodiments, transceiver 524 and antenna assembly 526 are also collectively configured to generate electrical or optical signals for processing subsystem 510 in response to RF signals received by antenna assembly 526, such as RF signals generated by UE device 504 for wirelessly transmitting information to wireless base station 502. Wireless subcarriers 506 are transmitted from wireless base station 502 to UE device 504, for example, through air and/or one or more other mediums capable of carrying wireless subcarriers 506. In certain embodiments, transmitting subsystem 508 is configured to generate wireless subcarriers 506 using an orthogonal frequency division multiplexing (OFDM) technique, such that wireless subcarriers 506 are orthogonal to each other. In some embodiments, transmitting subsystem 508 is configured to communicate with a plurality of UE devices (not shown) via wireless subcarriers 506.

Although FIG. 5 illustrates transmitting subsystem 508 as generating three or more wireless subcarriers 506, transmitting subsystem 508 may be configured to generate a different number of wireless subcarriers 506 without departing from the scope hereof. Additionally, wireless base station 502 is optionally configured such that the number of wireless subcarriers 506 generated by transmitting subsystem 508 is dynamically adjustable, such as a based on operating conditions of wireless base station 502 and/or configuration of UE device 504. Some or all of wireless subcarriers 506 may have a different form, such as a different amplitude, a different phase, a different shape (e.g. non-sinusoidal), and/or a different frequency, than the wireless subcarriers depicted in FIG. 5. For example, although FIG. 5 depicts wireless subcarriers 506 as having different respective amplitudes to show an example of dynamic allocation of transmission power among the wireless subcarriers (discussed below), wireless subcarriers 506 may have different amplitudes than those depicted in FIG. 5. As another example, although FIG. 5 illustrates wireless subcarriers 506 as being purely sinusoidal, i.e. having a single sinusoidal component, wireless subcarriers 506 could be composed of multiple components having different respective frequencies.

In particular embodiments, processing subsystem 510 is configured to execute instructions 514 stored in memory subsystem 512 to execute a method 600 for dynamic allocation of transmission power among wireless subcarriers. Method 600 is an embodiment of method 200 of FIG. 2 where the communication resource that is allocated is total transmission power of wireless base station 502. Instructions 514 include, for example, software and/or firmware.

In a block 602 of method 600, processing subsystem 510 executes instructions 514 to determine a risk-return characterization of a plurality of transmission power allocations among wireless subcarriers 506. In some embodiments, the risk-return characterization includes a respective risk and a respective return for each transmission power allocation. Each return is, for example, total data throughput of all wireless subcarriers 506, and each risk is, for example, a variation in total data throughput of all wireless subcarriers 506. Each transmission power allocation specifies how total transmission power of wireless base station 502 is allocated among wireless subcarriers 506. In some embodiments, processing subsystem 510 executes instructions 514 to randomly generate the plurality of transmission power allocations. The number of transmission power allocations considered in block 602 is chosen, for example, to achieve a desired trade-off between optimization of transmission power allocation and minimization of processing time.

Table 3 below illustrates one example of a risk-return characterization determined in block 602, in an embodiment where there are three wireless subcarriers 506 (N=3) and a risk-return characterization is determined for ten transmission power allocations A₁, A₂, A₃, . . . . A₁₀. Each transmission power allocation A_(i) corresponds to a particular set of weights, i.e. A_(i)={W_(i1), W_(i2), W_(i3)}, where the letter “i” is an index which ranges from 1 to 10 and corresponds to a particular transmission power allocation. W_(i1), W_(i2), and W_(i3) represent a portion of total transmission power of wireless base station 502 allocated to wireless subcarriers 506(1), 506(2), and 506(3), respectively. For example, transmission power allocation A₁ corresponds to 10%, 20%, and 70% of total transmission power of wireless base station 502 being allocated to wireless subcarriers 506(1), 506(2), and 506(3), respectively. Accordingly, if the total transmission power being allocated is 1.0 watt, 0.1 watt, 0.2 watt, and 0.7 watt of transmission power would be allocated to wireless subcarriers 506(1), 506(2), and 506(3), respectively, under transmission power allocation A₁.

TABLE 3 Allocation W_(i1) W_(i2) W_(i3) R_(i) V_(i) A₁ 10% 20% 70% 0.650 0.600 A₂ 15% 25% 60% 0.600 0.500 A₃ 21% 37% 42% 0.600 0.675 A₄  3% 47% 50% 0.300 0.225 A₅ 60% 27% 13% 0.525 0.400 A₆ 40% 40% 20% 0.400 0.400 A₇ 81%  9% 10% 0.525 0.475 A₈ 18% 60% 22% 0.675 0.700 A₉ 53% 27% 20% 0.350 0.500 A₁₀ 35% 35% 30% 0.425 0.300

Processing subsystem 510 executes instructions 514 to determine a respective return (R_(i)) and a respective risk (V_(i)) for each transmission power allocation A_(i) in the example of Table 3. For example, processing subsystem 510 determines that return R₁ and risk V₁ for transmission power allocation A₁ are 0.650 and 0.600, respectively, and processing subsystem 510 determines that the return R₂ and risk V₂ for transmission power allocation A₂ are 0.600 and 0.500, respectively. R_(i) represents total data throughput of all wireless subcarriers 506 using transmission power allocation A_(i), and V_(i) represents variation in total data throughput of all wireless subcarriers 506 using transmission power allocation A_(i). In some embodiments, processing subsystem 510 executes instructions 514 to determine return R_(i) and risk V_(i) from EQNS. 1 and 2 above, respectively. FIG. 7 is a graph 700 of return as a function of risk for the data of table 3, which has an efficiency frontier 702.

Referring again to FIG. 6, in block 604, processing subsystem 510 executes instructions 514 to select a first allocation of the plurality of transmission power allocations from the risk-return characterization according to at least one predetermined criterium. In some embodiments, the predetermined criterium is either a maximum return that can be achieved at a given risk or a minimum risk that can be realized at a given return. For example, assume that the predetermined criterium is to achieve maximum return at a risk of 0.400, given the scenario discussed above with respect to Table 3. The first allocation would be transmission power allocation A₅ because this transmission power allocation is on the efficiency frontier and achieves a maxim return (0.525) at a risk of 0.400, as can be seen in FIG. 7. As another example, assume that the predetermined criterium is to realize a minimum risk at a return of 0.600. The first allocation would be transmission power allocation A₂ because this transmission power allocation is on the efficiency frontier and achieves a minimum risk (0.500) at a return of 0.600, as can be seen in FIG. 7.

In block 606, processing subsystem 510 executes instructions 514 to automatically allocate transmission power among the plurality of wireless subcarriers 506 according to the first allocation. For example, assume that communication resource allocation A₂ of Table 3 is selected as the first allocation in block 604. In this example, processing subsystem 510 executes instructions 514 to automatically allocate transmission power among wireless subcarriers 506(1), 506(2), 506(3) according to set of weights {15%, 25%, 60%} of transmission power allocation A₂. For example, if the total transmission power of wireless base station 502 is 0.5 watt, processing subsystem 510 executes instructions 514 to control transmitting subsystem 508 such that 0.075 watt, 0.125 watt, and 0.300 watt are allocated to wireless subcarriers 506(1), 506(2), 506(3), respectively. Processing subsystem 510 is optionally further configured to execute instructions 514 to set modulation format, e.g. modulation order, of each wireless subcarrier 506 as a function of transmission power allocated to the wireless subcarrier 506. Accordingly, allocating total transmission power using method 600 promotes high-capacity of wireless base station 502 while helping minimize fluctuation in capacity.

In some embodiments, processing subsystem 510 is configured to execute instructions 514 to perform method 600 periodically and/or in response to a change in operating conditions of communication system 500. Such repeated performance of method 600 advantageously helps communication system 500 adapt to changes in its operating environment, such as due to interference from other wireless base stations, thereby promoting high-performance of communication system 500 under dynamic conditions.

UE device 504 is optionally configured to allocate transmission power among wireless subcarriers (not shown) transmitted from UE device 504 to wireless base station 502, in a manner similar to that discussed above with respect to FIG. 6. For example, in some embodiments, UE device 504 is configured to execute a variation of method 600 where the transmission power to be allocated is total transmission power of UE device 600, instead of total transmission power of wireless base station 500.

The methods discussed above for dynamic allocation of communication resources can be applied to allocate communication resources among multiple devices in a system, e.g. among multiple wireless access points in an array of wireless access points. For example, FIG. 8 is a block diagram of a communication system 800 including a plurality of wireless base stations and configured to dynamically allocate transmission power. Communication system 800 includes a plurality (N) of wireless base stations 802 and a controller 804. Each wireless base station 802 is, for example, a LTE wireless base station (e.g., an eNB device), a 5G NR wireless base station (e.g., a gNB device), a 6G wireless base station, a Wi-Fi wireless base station (e.g., including unscheduled, partially scheduled, and unscheduled systems), a satellite wireless base station, or variations and/or extensions thereof. Although FIG. 8 illustrates communication system 800 as including three or more wireless base stations 802, communication system 800 could include only two wireless base stations 802 without departing from the scope hereof.

Each wireless base station 802 is configured to communicate with one or more UE devices 806 via a respective wireless communication channel 808. For example, wireless base station 802(1) communicates with UE devices 806(1)-(3) via a wireless communication channel 808(1), and wireless base station 802(2) communicates with UE devices 806(4)-(5) via a wireless communication channel 808(2). Accordingly, wireless communication channels 806 are embodiments of communication channels 106 of FIG. 1. Each wireless communication channel 808 includes wireless signals, symbolically shown by arrows 809, transmitted between respective a wireless base station 802 and one or more UE devices 806. The wireless signals are transmitted, for example, through air and/or one or more other mediums capable of carrying wireless signals. In some embodiments, the wireless signals are generated by wireless base stations 802 and/or UE devices 806 using OFDM techniques. Only two arrows 809 are labeled in FIG. 8 to promote illustrative clarity.

Although UE devices 806 are depicted as mobile phones, one or more UE devices 806 could take a different form, such as a computer, a set-top device, a data storage device, an IoT device, an entertainment device, a wireless access point (including, for example, eNBs, gNBs, and Wi-Fi APS acting as UEs), a computer networking device, a smartwatch, a wearable device with wireless capability, or a medical device. The number of UE devices 806 being served by communication system 800, as well as the number of UE devices 806 being served by each wireless base station 802, may vary without departing from the scope hereof UE devices 806 are not necessarily part of communication system 800.

Controller 804 includes a processing subsystem 810 and a memory subsystem 812. Processing subsystem 810 is configured to execute instructions 814 stored in memory subsystem 812 to control at least some aspects of communication system 800. Instructions 814 include, for example, software and/or firmware. Although wireless base stations 802, processing subsystem 810, and memory subsystem 812 are each symbolically shown as a single element, one or more of these elements may include a plurality of constituent sub-elements. For example, processing subsystem 810 could include a plurality of processors, and memory subsystem 812 could include a plurality of memory modules. As another example, one or more wireless base stations 802 could include an antenna assembly that is remote from a radio control device. Additionally, the elements and sub-elements of communication system 800 could be distributed in multiple locations. For example, processing subsystem 810 could include multiple processors distributed among two or more data centers, and memory subsystem 812 could include multiple memory devices distributed among a plurality of data centers. Furthermore, two or more elements of communication system 800 could be combined. For example, controller 804 could be incorporated in one wireless base station 802 instance, or controller 804 could be a distributed controller collectively incorporated in multiple wireless base station 802 instances.

In particular embodiments, processing subsystem 810 is configured to execute instructions 814 to execute a method 900 for dynamic allocation of transmission power among wireless communication channels 808. FIG. 9 is a flow chart illustrating method 900.

In a block 902 of method 900, processing subsystem 810 executes instructions 814 to determine a risk-return characterization of a plurality of transmission power allocations among wireless communication channels 808. In some embodiments, the risk-return characterization includes a respective risk and a respective return for each transmission power allocation. Each return is, for example, total data throughput of all wireless communication channels 808, and each risk is, for example, a variation in total data throughput of all wireless communication channels 808. Each transmission power allocation specifies how a total transmission power of all wireless communication channels 808 is allocated among wireless communication channels 808. In some embodiments, processing subsystem 810 executes instructions 814 to randomly generate the plurality of transmission power allocations. The number of transmission power allocations considered in block 902 is chosen, for example, to achieve a desired trade-off between optimization of transmission power allocation and minimization of processing time.

Table 4 below illustrates one example of a risk-return characterization determined in block 902, in an embodiment where there are three wireless communication channels 808 (N=3) and a risk-return characterization is determined for ten transmission power allocations A₁, A₂, A₃, . . . . A₁₀. Each transmission power allocation A_(i) corresponds to a particular set of weights, i.e. A_(i)={W_(i1), W_(i2), W_(i3)}, where the letter “i” is an index which ranges from 1 to 10 and corresponds to a particular transmission power allocation. W_(i1), W_(i2), and W_(i3) represent a portion of total transmission power of all wireless communication channels 808 allocated to wireless communication channels 808(1), 808(2), and 808(3), respectively. For example, transmission power allocation A₁ corresponds to 20%, 70%, and 10% of total transmission power of all wireless communication channels 808 being allocated to wireless communication channels 808(1), 808(2), and 808(3), respectively. Accordingly, if the total transmission power being allocated is 1.0 watt, 0.2 watt, 0.7 watt, and 0.1 watt of transmission power would be allocated to wireless communication channels 808(1), 808(2), and 808(3), respectively, under transmission power allocation A₁.

Processing subsystem 810 executes instructions 814 to determine a respective return (R_(i)) and a respective risk (V_(i)) for each transmission power allocation A_(i) in the example of Table 4. For example, processing subsystem 810 determines that return R₁ and risk V₁ for transmission power allocation A₁ are 0.300 and 0.225, respectively, and processing subsystem 810 determines that the return R₂ and risk V₂ for transmission power allocation A₂ are 0.400 and 0.400, respectively. R_(i) represents total data throughput of all wireless communication channels 808 using transmission power allocation A_(i), and V₁ represents variation in total data throughput of all wireless communication channels 808 using transmission power allocation A_(i). In some embodiments, processing subsystem 810 executes instructions 814 to determine return R_(i) and risk V_(i) from EQNS. 1 and 2 above, respectively. FIG. 10 is a graph 1000 of return as a function of risk for the data of Table 4, which has an efficiency frontier 1002.

Referring again to FIG. 9, in block 904, processing subsystem 810 executes instructions 814 to select a first allocation of the plurality of transmission power allocations from the risk-return characterization according to at least one predetermined criterium. In some embodiments, the predetermined criterium is either a maximum return that can be achieved at a given risk or a minimum risk that can be realized at a given return. For example, assume that the predetermined criterium is to achieve maximum return at a risk of 0.400, given the scenario discussed above with respect to Table 4. The first allocation would be transmission power allocation A₅ because this transmission power allocation is on the efficiency frontier and achieves a maximum return (0.525) at a risk of 0.400, as can be seen in FIG. 10. As another example, assume that the predetermined criterium is to realize a minimum risk at a return of 0.400. The first allocation would be transmission power allocation A₂ because this transmission power allocation is on the efficiency frontier and achieves a minimum risk (0.400) at a return of 0.400, as can be seen in FIG. 10.

In block 906, processing subsystem 810 executes instructions 814 to allocate transmission power among the plurality of wireless communication channels 808 according to the first allocation. For example, assume that communication resource allocation A₂ of Table 4 is selected as the first allocation in block 904. In this example, processing subsystem 810 executes instructions 814 to control wireless base stations 802 to automatically allocate transmission power among wireless communication channels 808(1), 808(2), 808(3) according to set of weights {15%, 60%, 25%} of transmission power allocation A₂. For example, if the total transmission power of all wireless communication channels 808 is 0.5 watt, processing subsystem 810 executes instructions 814 to control wireless base stations 802 such that 0.075 watt, 0.300 watt, and 0.125 watt are allocated to wireless communication channels 808(1), 808(2), 808(3), respectively. Accordingly, allocating total transmission power using method 900 promotes high-capacity of communication system 800 while helping minimize fluctuation in capacity.

In some embodiments, processing subsystem 810 is configured to execute instructions 814 to perform method 900 periodically and/or in response to a change in operating conditions of communication system 800. Such repeated performance of method 900 advantageously helps communication system 800 adapt to changes in its operating environment, such as due to interference from other wireless communication systems, thereby promoting high-performance of communication system 800 under dynamic conditions.
